C Compiler cannot create executables on Mac

[Tristan Slominski]

Hey,

I am new to Mac and I can't get the source to compile. When I run ./
configure I get the following error:

checking build system type... i386-apple-darwin10.0.0
checking host system type... i386-apple-darwin10.0.0
checking target system type... i386-apple-darwin10.0.0
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... no
checking for mawk... no
checking for nawk... no
checking for awk... awk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

Anyone know how to fix this?

Thanks,

-Tristan

What does config.log say?

[Tristan Slominski]

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Protocol Buffers configure 2.2.0, which was
generated by GNU Autoconf 2.61. Invocation command line was

As the original message suggested, it looks like your compiler doesn't work -- it was unable to compile a no-op program (shown below).  Maybe you need to reinstall it.

[Tristan Slominski]

Could it be that conftest.c never gets generated? When I look at the
directory... I see conftest.h popup into existence, but never
conftest.c

[Tristan Slominski]

Looks like I was accidentally downloading some really old Xcode... I'm
updating to the latest version now, I hope that solves the problem.

The configure script is generated by autoconf which is used by thousands of open source projects.  So, it's unlikely that it is the problem.

[Tristan Slominski]

As I indicated above. I got lost on the apple developer site and
downloaded the old Xcode. I updated to the latest one and everything
worked like a charm.
